  • A handful of fresh chopped cilantro

Preparation: how to make Tuna Tostadas, step by step

1. Prepare the tuna

  • Wash and cut the tuna: Remove excess water and cut the tuna into small cubes (~1 cm). This will make it easier to mix with the other ingredients and ensure the flavor is evenly distributed.

2. Mix fresh ingredients

  • Combine onion, chili, and cilantro: In a separate bowl, combine the finely chopped white onion, the serrano chili cut into small pieces, and the fresh cilantro. This will add an aromatic and spicy flavor that will enhance the dish.

3. Incorporate the tuna

  • Combine the mixture: Add the onion, chili, and cilantro to the bowl with the tuna. Season with salt and pepper to taste and mix carefully so that all ingredients are integrated without breaking up the fish.

4. Add the passion fruit sauce

  • Incorporate mayonnaise and lemon: Add 2 tablespoons of macha mayonnaise and the juice of half a lemon. Continue mixing gently so that the tuna remains juicy and well seasoned.

5. Add the avocado

  • Incorporate the fruit: Add the avocado cubes and mix with gentle movements so as not to break them, allowing their creamy texture to contribute to the contrast of flavors.

6. Assemble the tostadas

  • Assemble the presentation: Place the tostadas on a plate and generously distribute the tuna filling on each one. Decorate with finely grated carrot and a few drops of lemon juice for a sour and fresh touch.

7. Finish and serve

  • Final touch: Sprinkle a little coarse salt over the tostadas and add a few drops of lemon juice. Serve immediately to enjoy the crispy texture and freshness of the ingredients.

To finish and serve

Before serving, adjust the seasoning if necessary, aiming for a balance between the flavor of the fish and the vegetables. Use modern or traditional plates, as you prefer. La Reina del Mar recommends accompanying these tostadas with a fresh salad or some radish slices to enhance the maritime experience. Enjoy in company, at an informal lunch or a light dinner that will surprise all diners!


Tips: how to perfect your Tuna Tostadas

  • Tuna freshness: Always use high-quality tuna, preferably fresh or canned from a good brand, such as Ortiz or Pescamar. The quality of the fish makes a difference in flavor and texture.
  • Flavor balance: Adjust the amount of chili and lemon to your taste, but without overdoing it to maintain a mild but vibrant flavor.
  • Texture of the filling: The crunchy touch of grated carrot and various toppings provide contrast; experiment with other ingredients such as radishes, cucumber, or corn chips.

  • Ideal pairing: These tostadas pair perfectly with a cold beer, mineral water with lemon slices, or a white wine fresh one like those from Villa del Sur winery.
